STDEVP
TheSTDEVP
function calculates the standard deviation of an entire population. It is commonly used in statistical analysis to measure the amount of variation or dispersion in a set of data. This function takes in at least two numerical arguments representing the values in the population for which you want to calculate the standard deviation.

Usage
Use the STDEVP
formula with the syntax shown below, it has 1 required parameter and 1 optional parameter:
 value1 (required):
The first numerical value or range of values in the population for which you want to calculate the standard deviation.  value2 (optional):
Optional. Additional numerical values or ranges of values in the population for which you want to calculate the standard deviation.
Examples
Here are a few example use cases that explain how to use theSTDEVP
formula in Google Sheets.
Calculate the standard deviation of an entire population
Use STDEVP
to calculate the standard deviation of a set of data that represents an entire population. This can help you measure the amount of variation or dispersion in the data.
Compare the variability of two populations
Use STDEVP
to calculate the standard deviation of two populations and compare their variability. This can help you determine whether the two populations are significantly different.
Analyze data in a scientific experiment
Use STDEVP
to analyze data in a scientific experiment and calculate the standard deviation of the results. This can help you determine the degree of precision and accuracy of the experiment.
Common Mistakes
STDEVP
not working? Here are some common mistakes people make when using the STDEVP
Google Sheets Formula:
Using nonnumeric values
The STDEVP
function only works with numerical values. If you use nonnumeric values as input, the function will return an error. Make sure to check that all input values are numerical.
Forgetting to include all values
The STDEVP
function requires at least two input values. If you forget to include all values, the function will return an error. Make sure to check that all required input values are included.
Using a range of cells with empty cells
If you use a range of cells as input that contains empty cells, the STDEVP
function will include these empty cells in the calculation, which may result in an incorrect output. Make sure to only include cells with numerical values.
Related Formulas
The following functions are similar to STDEVP
or are often used with it in a formula:

STDEV
The
STDEV
function calculates the standard deviation of a set of numbers. It measures the amount of variation or dispersion of a set of values from the average (mean) value. It is commonly used in statistics to determine the spread of a data set. The values can be supplied as individual cells, ranges, or constants. 
AVERAGE
The AVERAGE function calculates the average (arithmetic mean) of the values passed to it. It is commonly used to find the average of a range of cells containing numerical data.

VAR
The
VAR
formula calculates the variance of a set of numerical values. Variance is a measure of how spread out a set of data is in relation to the mean. This formula is commonly used in statistical analysis to measure the variability or diversity of a dataset. 
VARP
The
VARP
function is a statistical function in Google Sheets that returns the variance of a population based on a set of values. Variance is a measure of how spread out a set of data is from its average value. This function is commonly used in statistics and data analysis.
